PROBLEM TO BE SOLVED: To provide a radial tire for an aircraft.SOLUTION: In a tire-width directional cross-section upon the standard state, intersections of a straight line M which passes through a center A of a bead core 1a and is vertical to a tire-width direction and a tire inner surface are put as P and Q. In the tire-width directional cross-section upon the triple load state, a point located on the outermost side is put as R. A tire is provided with a belt 4 and, when the tire is divided into a center part and a shoulder part on the basis of a straight line L which passes through a point B of the tip of a bead toe 8 and is vertical to the tire width direction, the belt is configured such that the number of layers on the shoulder part is smaller than the number of layers on the center part, and a radially innermost side position D1 of a belt layer on the radially innermost side on the shoulder part is located on the radially inner side than a radially innermost side position D2 of a belt layer 4a on the radially innermost side of the center part. Upon the triple load state, the P is located on the tire radially outer side than the straight line QP made by connecting the point Q on the tire inner surface on tire equatorial surface and the point R. |
